FAST Engine Control System XFI - Sportsman TB

The FAST XFI Sportsman Engine Control System is a bank-to-bank, fully software-tunable EFI setup designed for a wide range of applications, including muscle cars, late model street vehicles, sportsman drag racing, and boosted engines. It offers advanced control over fueling, timing, and air/fuel targets, making it a powerful option for those looking to optimize engine performance. This system is compatible with both naturally aspirated and boosted applications up to 5 BAR, and can handle wet nitrous systems with integrated timing retard control.

You can tune your engine using the included FAST C-COM software and USB cable on your laptop. The system supports both Speed Density and Alpha-N fuel strategies, giving you flexibility depending on your needs. For drag racers seeking absolute consistency, the Alpha-N option is particularly beneficial. Data logging is also built-in, allowing you to monitor and analyze engine performance. The ECU enclosure is waterproof, and diagnostic LEDs are integrated for easier troubleshooting. Connectivity is straightforward with built-in CAN network support for components like the EZ-TCU and XIM, and it works with a variety of multi-port systems or either generation of the FAST EZ-EFI throttle body. It's also configurable to work with different ignition systems, including FAST distributors, crank triggers, or even aftermarket CD ignition boxes.

This system is designed for use with high-impedance injectors and is compatible with both return-style and returnless fuel systems. It includes a Bosch wide-band 02 sensor and a premium, mesh-type wire loom multi-port harness. A version is available that includes a 4150-style, eight-injector, 1200-horsepower-capable throttle body for easier upgrades from carbureted setups. Please note that this system is not CARB approved and cannot be shipped to California.
